/* How does this DLL work?
* This DLL is used to probe and configure wireless access points using the
* available wireless interfaces. Most functions are tied to a handle that is
* first obtained by calling WlanOpenHandle. Usually it is followed by a call
* to WlanEnumInterfaces and then for each interface a WlanScan call is made.
* WlanScan starts a parallel access point discovery that delivers the ready
* response through the callback registered by WlanRegisterNotification. After
* that the program calls WlanGetAvailableNetworkList or WlanGetNetworkBssList.
